tail --follow is useful to see what is being added to a file. However,
if the monitored file is followed for a certain period, it doesn't
indicate when the new content was added. It would be nice if tail
allowed to prepend timestamps to the output, as MultiTail's -ts option does.
This is a little delicate to do. The timestamp could be prepended to
each line, or only to each atomic addition to the file. Also, as we
don't know when the existing lines were added, we can't give them an
exact timestamp. MultiTail stamps them with the time of MultiTail's
launch, but I find that a bit misleading. I would consider simply not
stamping these.
In any case, as this alters the output, this should be optional.
Scanning the changelog suggests this has not been implemented as of 8.21.
